Analysis Note:	These secondary standards offer multi-traceability to the USP and EP primary standards, where they are available.
Application:	Orphenadrine Citrate may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations by chromatography as well as spectrophotometry techniques.
Application:	These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.
Biochem/physiol Actions:	Muscarinic receptor antagonist; H₁ histamine receptor antagonist; muscle relaxant. Orphenadrine has also been reported to inhibit the noradrenergic transporter and to block the NMDA receptor ion channel.
General description:	Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards. Orphenadrine Citrate is an analog of diphenhydramine antihistamine drug. It operates as a centrally acting skeletal muscle relaxant and effectively serves to relieve painful skeletal muscle spasms by working as an analgesics.
Other Notes:	This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.
